Friendship is a very common theme. Gon and Killua have a strong bond, and many fanfictions explore how this friendship grows and endures different trials. For example, they might face a powerful enemy together and their friendship is what helps them get through it.
One popular 'hunter x hunter gon x killua fanfiction' is 'The Bonds Beyond'. It beautifully explores their deep friendship and the adventures they could have had beyond the main storyline. It has great character development and some really heart - warming moments between Gon and Killua.
One common theme in fanfics about Killua's sister is her growth and development. Writers may show her learning more about the world, becoming more independent, and perhaps even using her powers for good. She might go on adventures, similar to the main characters in Hunter x Hunter, and meet new and exciting people along the way.
There's a fanfic called 'Hisoka's Obsession with Machi'. It delves into Hisoka's perspective. He is constantly intrigued by Machi's skills and her cold exterior. The story has some interesting scenes where Hisoka tries to get closer to Machi, and Machi is both repelled and fascinated by him at the same time. It's a really engaging read.
In the Hunter x Hunter manga, the focus isn't on whether Gon smells or not. The story is more about the adventures and character development. So, the answer is no, there's no such aspect depicted.
The themes usually revolve around family as well. His complex relationship with the Zoldyck family is often explored. Some fanfictions show him trying to reconcile with his family or completely break away. Adventure is another common theme. Since he's a Hunter, fanfictions often send him on exciting adventures, facing new monsters and challenges, which is in line with the spirit of the original 'Hunter x Hunter' series.
One common theme is growth. Fans often write about Gon growing in power and wisdom. For example, in many fanfictions, Gon discovers new Nen abilities and learns how to control them better.
Themes are important too. In a Hisoka x Machi fanfic, themes like love - hate relationships, power dynamics, or self - discovery can be explored. For instance, Machi might discover a new side of herself through her interactions with Hisoka. And the fanfic should be well - written in terms of grammar and style, so that the reader can fully immerse themselves in the world of Hunter x Hunter and the relationship between Hisoka and Machi.
The plot could also involve her having unique nen abilities different from Hisoka's. She might be on a journey to understand these powers and in the process, cross paths with the main characters from Hunter x Hunter. Perhaps she forms an unlikely alliance with Gon and Killua, who initially are wary of her because of her relation to Hisoka, but later come to respect her for her own qualities.
One great 'Hunter x Hunter Killua fanfiction' is 'Killua's New Adventure'. It takes Killua on a journey where he discovers a hidden power within himself. Another is 'Killua and Gon's Reunion' which focuses on their friendship after a long separation. There's also 'Killua's Training Days' that delves deep into his training regime and how he overcomes various challenges during it.
